https://github.com/roberthein/tinyconstraintsA Swift library providing syntactic sugar for Auto Layout to make constraint creation shorter and more readable. Features include shorthand for edge and center constraints, a stack method for grouping views, and constraints that are active by default.
You can install TinyConstraints using CocoaPods, Carthage, or Swift Package Manager.
### CocoaPods
```ruby
pod "TinyConstraints"github "roberthein/TinyConstraints"Add the following repository URL in Xcode:
https://github.com/roberthein/TinyConstraints.gitTo animate a constraint, store the constraint object and update its .constant property within a layout animation block.
let height = view.height(100)
// Animate change
height.constant = 200
UIViewPropertyAnimator(duration: 1, dampingRatio: 0.4) {
self.layoutIfNeeded()
}.startAnimation()Use the stack method on a superview to constrain a collection of views together with a specific axis and spacing.
let views = [logo, title, description]
superview.stack(views, axis: .vertical, spacing: 10)You can specify the relation (default is .equal) and priority (default is .required) when creating constraints.
container.width(150, relation: .equalOrLess, priority: .high)Constraints are active by default. To create inactive constraints that you can manage later, set isActive: false. You can then use .activate() or .deActivate() on a Constraints object.
// Create inactive constraints
let constraints = view.size(CGSize(width: 100, height: 100), isActive: false)
// Activate them later
constraints.activate()
// Deactivate and activate in an animation
oldConstraints.deActivate()
constraints.activate()
UIViewPropertyAnimator(duration: 1, dampingRatio: 0.4) {
self.layoutIfNeeded()
}.startAnimation()Constraint for NSLayoutConstraint and Constraints for [NSLayoutConstraint].center(in:) to constrain the center of a view to its superview, optionally providing an offset.edgesToSuperview() to attach all four edges of a view to its superview. You can provide insets or exclude specific edges.
